Windows 7: Can't boot USB 3.0 Flash Drive from USB 3 Port

I made a bootable ADATA 16GB USB 3.0 flash drive using LIli. Also used Yumi to make bootable flash drive. Either way it will not boot when plugged in a USB 3 port.
It does not show up using BBS popup(F8). Nor does it show up in the bios.
It will boot when plugged in a USB 2.0 port.

Also, I can make a bootable USB 2.0 flash drive and can boot from it when plugged in 3.0 port. It shows up in the bios and the BBS popup.

I have tried everything possible. No luck. I'm stumped.
I have the latest bios and driver for this Renesas Electronics USB 3.0 Host Controller.

Like GeneO said, if you have an option for legacy USB in your bios enable it. What it does is allows USB 2.0 devices to run on USB 3.0 ports. (Yes I know it should be that way anyway, but...) That should allow you to boot from those ports although it will be at USB 2.0 speed. The drivers that enable USB 3.0 are in the OS and do not load until the OS loads.

What about USB 3.0 point devices being allowed to run on USB 3.0 ports (on a card such as Renesas)?

Just asking for technical info, because if the speed will be at USB 2.0, the only thing it can help is the location of the cord (convenience -being close, ports being on left or right of the computer-, cord size, etc.)
